The National Investigation Agency (NIA) on Wednesday carried out search operations in seven places in Tamil Nadu’s Coimbatore, including the residence of a social media friend of the Sri Lanka Easter blast mastermind, officials said.

The searches were carried out in connection with the NIA probe into the new Islamic State module case.

According to ANI, the leader of ISIS module, Mohammad Azharuddin, was found to be friends with Sri Lanka Easter blast mastermind Zahran Hashim on Facebook.

However, it is not yet known if Azharuddin was also associated with other Sri Lanka Easter bombing attackers.

An NIA official in New Delhi told IANS that the agency had registered a case 10-12 days ago in connection with the new ISIS module.

Last month, the NIA carried out searches at 10 places in Tamil Nadu in connection with the investigation into an Islamic State module case, where few people conspired to raise funds and wage armed struggle against the State.

The disastrous serial bomb blasts targeting churches and hotels in Sri Lanka on Easter Sunday had claimed over 250 lives. The ISIS had taken responsibility for the attacks.
